Random Materials is an add-on that automatically assigns materials to selections with a single click. The tool operates at the object, mesh island, or individual face level, generating random material variations across geometry.

Users can generate material variations using a defined hue, saturation, and value range, or by pulling from a custom color palette. The add-on also provides global overwrite controls for material properties, allowing users to independently adjust metallic, roughness, IOR, and alpha values across the randomized materials to maintain visual consistency.
